Jun 1, 2026June 2026: Focused on advancing Vault test automation reliability and maintainability. Delivered a Robust Vault Test Automation Framework Enhancement that includes a comprehensive test automation guide for Enos, enhancements to the blackbox testing framework with version-based test skipping, and dynamic timeout calculations based on test counts. Also refined metadata handling in scenarios to reduce flakiness and improve maintainability. Performed backport of VAULT-44278: Add Min Vault Version to Blackbox Tests into ce/main, driven by commit 53e3710939bd524a2ffd3478406a3010dcaa3513 (from vault_automation/tin). Result: more reliable, scalable test suites with better version awareness, enabling faster feedback and safer releases.
